ABSTRACT:
A process for the isomerization of a tertiary double bonded olefin having a hydrogen atom attached to a carbon atom vicinal to the tertiary carbon of the double bond comprises treating the olefin in a solution of dry liquid sulfur dioxide in the presence of a catalyst selected from oxygen, a hydroperoxide or a protic acid or mixtures thereof.
